How to get to 650whp with 98 octane

Hi guys! Been looking around the forum for a while to get grips on how to mod the LSA properly. Im quite new to V8s and supercharged motors really, after having driven all-motor Japanese cars my life. I just acquired an 09 CTS-V sedan in pristine condition. I'm looking to build a 650whp daily driver but not really certain which mods to buy at this point. I'm very particular about maintaining daily drivability. What mods does everyone recommend should I go with to achievr 650whp on 98 octane gas reliably? Thanks for the input in advance!

As for what you are looking to do. We have a bunch of products that have all been thoroughly tested and validated. They would certainly fit the bill. Check out our website for more details on the various power kits we offer.

It's 98 RON. That's the octane rating of premium fuel here in Dubai. I think the regular is about 96

Are you auto or manual?

Upgrade HX
Upper and lower pullies
160 stat
ZR1 cam (you could go more aggressive but the ZR1 cam will be pure stealth)
Headers or offroad pipes with stock manifolds. (stock manifolds are a work of art)
Tune specific to higher octane fuel

If you are a manual you may need a clutch...not sure how the autos are holding at that that power level

Hi Chris thanks for the response! What pullies do you recommend? The car is auto by the way with a GM differential cooler which is standard in this part of the world due to heat. Yeah I'm planning to stick to the stock exhaust but I might consider swapping the headers to either kooks or AR. How's drivability with GT9 cams?

Re: How to get to 650whp with 98 octane

Custom cam or gt9 is fine you will just need to run some very good valve springs. The gt9 isn't 100% stealth but close.
Great heat exchanger
Jabsco intercooler pump
Norcal intercooler tank
Guard dog lid spacer with 8 meth nozzles
2.5" upper
8.6 lower
Long tube headers
Ported blower but you can just do the snout. Doing the 102mm tb is killer though.
As you can see I'm really focused on extra cooling. With the extra boost you will be increasing your intake air temp.

Thanks for the input Josh. I agree on the cooling side. Since I'm here in Dubai, and summer here literally sizzles, I really need to address cooling issues ahead.

With 2.5 upper and 8.6 lower, what kind of boost will I be looking at?

By the way, I don't think I'll be able to pass on the annual inspection if I use meth. I also think meth isn't readily available here so that will pose another problem.
